Determination of debye-waller factor and synthesis of silver oxide powder particles from X-ray diffraction and combustion technique

In this paper, we have been presented the Combustion synthesis technique and determination of Debye-Waller factor, Debye temperature, mean square amplitude of vibrations and the particle size of silver oxide (AgO) powder particles. Combustion technique has been adapted to synthesis the AgO powder particles material using silver nitrate as oxidizer and glycine as fuel. X-ray diffraction study has been adapted to determine the solid state parameters like Debye-Waller factor, Debye temperature and mean square amplitude of vibrations and particle size of silver oxide powder particles. The integrated intensities have been recorded for this powder sample with JEOL JDX – 8P upgraded X-ray powder diffractometer fitted with a NaI (TI) scintillation counter using filtered CuKα radiation at room temperature and have been corrected for TDS (Thermal Diffuse Scattering) effect. Debye-Waller factor has determined as 0.22 Ų. The particle size has been estimated from Hall-Williamson plot and it has been found as 294 nm. The Debye temperature has been determined as 366 K. The value of Debye temperature obtained in the present work has been used to estimate vacancy formation energy (E_f) of AgO powder particles. The Debye temperature value obtained in the present work has also been compared with the value obtained from other methods. The values of E_f are not available for comparison.
